The Goodman 10716005 Natural Gas Orifice (burner spud) is a genuine OEM gas-metering component for AMH81005CXBD furnaces and compatible Goodman/Amana models. The orifice threads into the manifold and meters the precise volume of natural gas fed to each in-shot burner. A damaged, corroded, or incorrectly drilled orifice causes over- or under-firing, sooting, and poor efficiency — so exact sizing matters.
The orifice bore diameter directly sets the firing rate. OEM 10716005 is factory-drilled to the exact size this furnace requires. Generic or mis-labeled orifices can shift the BTU output enough to trip limits or produce carbon monoxide. For a gas-metering part, OEM precision is essential.
Easy to Moderate — Shut off gas and power, remove the burner in front of the orifice, and unscrew the spud with a proper socket to avoid rounding the hex. Apply approved thread sealant only where specified, then leak-check with the gas back on. Replace all orifices as a set for even firing.
